It's time for the BHAF to go, and I plan to get an AEM DryFlow filter, but which one?

This conical one is 9" long with 1" deep pleats (P/N 21-3059DK)...the link shows is the regular pleat P/N. Cheapest I found online is $48.14 shipped

OR

This oval one (P/N 21-2259DK) for $71.96 shipped.

Except for a little more filter surface area I can't see spending the extra $20, and pretty much every twins setup I see guys running a conical filter like the first one...most likely due to lack of space, but if guys can run twins with a filter like that then I'm sure my stock turbo will be just fine.
Of all the info I could find online about these filters, 99% of it was good, and rather than buying the AEM cleaning kit, I recently read about a guy who has been using diluted Simple Green with positive results.
What do you guys think?
